Abstract:

In the present study, we have introgressed two major genes, viz., Xa21 and Pi54 conferring resistance against bacterial blight (BB) and blast, respectively into an Indian rice variety MTU1010. Breeding line of Akshyadhan (RP6132) possessing Xa21 and Pi54 was used to transfer the target traits into the susceptible parent MTU1010, which is highly susceptible to both BB and blast diseases, which limits its spread to the disease endemic areas. Hence, an attempt was made to incoporate BB (Xa21) and blast (Pi54) resistance genes from breeding line of Akshyadhan which is highly resistant to the rice bacterial blight and blast diseases caused by the pathogen, Xanthomonas oryzae pv. oryzae (Xoo) and blast fungus Magnaporthe grisea respectively. The SES scale (IRRI, SES 2013) was used for visual scoring of bacterial blight and blast resistance in the segregating population and the resultant resistant progenies were advanced. This work demonstrates the successful application of Mendelein ratio for targeted introgression of a dominant BB and blast genes (Xa21 + Pi54) into a most popular rice variety, MTU 1010, a short duration, high yielding; long slender rice variety occupied maximum area in India particularly during dry-season. Our study exemplifies the improvement of the targeted popular variety MTU1010 for the multiple target traits.
